This study suggested the satisfaction of middle-aged women with dance sports according to its participation type and activation methods of dance sports facilities and conducted questionnaire with total 450 middle-aged women who are participating in dance sports in G metropolitan city in order to offer the basic materials for creating efficient investment and economic profitability of dance sports facilities and data collected were analyzed with SPSS 11.0. One-way ANOVA for analyzing their frequency and satisfaction according to participation type on demographical factors and participation types and activation methods according to participation type in dance sports and multiple correlation analysis for analyzing the relationship between participation type and activation methods were conducted and the following conclusions were obtained. 1. In analysis of participation type of middle-aged women in dance sports, most of them participated in dance sports less than 3 months, frequency of participation in it a week was twice and hours of dance sports was mostly less than 1 hour, 2. In satisfaction of middle-aged women with the period and frequency of participation in dance sports, achievement factor, social factor, leisure and health factors showed statistically significant differences, but participation hours showed significant differences in social, leisure and health factors except achievement factor (p<.05). 3. Study on activation method showed that group participating in dance sports for more than 6 months emphasized the activation of facilities and group participating in dance sports for less than 3 months did that of coach, Group having the career of sports dance between 3 and B months responded program should be activated and improved, On activation of facilities and programs, groups participating in dance sports three times and four times a week had high concerns on it. 4. In correlation analysis between participation type in dance sports and activation methods, participation period and facilities, coach and program showed higher correlations and frequency of participation in dance sports showed higher correlations between coach and program activation, but there was no correlation between facility, coach and program activation according to participation hours.

Tandem SAW process with high heat input is widely used on steel fabrication industries to enhance the productivity by decreasing the melding layers on comer joint of box column. In this process the crack occurred in partial penetration joint. because of carbon contents. high cooling rate. welding groove and welding speed. Otherwise crack &d not occur in full penetration joint. because of - decreasing carbon dilution from base metal. - improving welding condition between weld surface width and weld depth. - low carbon equivalent by GMAW.

Multiloop Edgewise Arch Wire의 tip back 정도에 따른 응력 분포에 관한 유한요소법적 연구

이영일,차경석,주진원,이진우 대한치과교정학회 2000 대한치과교정학회지 Vol.30 No.2

임상에서 다양하게 사용되는 Multiloop Edgewise Arch Wire(MEAW)는 구치부 치아의 치축 직립을 위해 Ⅱ급 고무줄이나 수직고무줄과 함께 사용된다. 이때 tip backbend의 정도는 각 환자의 구치치축의 근심경사의 정도에 따라 가감이 결정되나 이 장치가 실제 치근막에서 어떤 효과를 나타내는지 정확히 알려진 바는 없다. 이에 저자는 MEAW의 역학적 효과를 알아보기 위해 tip back bend의 정도를 변화시킨 후 Ⅱ급 고무줄, 수직고무줄을 적용시켜 유한요소법을 통해 치근막에서 발생되는 응력의 분포와 크기를 정량적으로 비교, 관찰하여 장치의 역계를 이해하고 치료효과를 예측해 보고자 실험을 고안하였다. 발치나 교정치료의 경험이 없는 25세 남자 정상교합자를 대상으로 컴퓨터 단층촬영을 시행하여 얻은 방사선필림을 기초로 하여 유한요소 상악치아모델과, 치근막모델을 제작하였으며 여기에 beam element로 제작된 MEAW의 tip back bend를 5도, 10도, 15도로 달리하여 Ⅱ급 고무줄 및 수직고무줄을 적용시켜 각 치근막에서의 압축, 인장력의 분포와 응력의 크기를 상호 비교한 결과 다음과 같은 결론을 얻었다. 1.MEAW에 tip back bend를 5도, 10도, 15도로 부여하고 Ⅱ급 고무줄이나 수직고무줄을 적용시켰을때 전체 치근막에 나타나는 압축, 인장의 분포는 Ⅱ급 고무줄, 수직고무줄 각각의 경우에서 tip back bend의 정도에 상관없이 유사한 양상을 나타냈다. 2.각 치아의 치근막에 나타난 압축, 인장력의 크기는 5도, 10도의 경우보다 15도 tip back bend 부여시 더 크게 나타났다. 3.제1, 2대구치 원심측 치근막에서는 압축력이 나타났으며 특히 제2대구치 치근막의 압축부위가 제1대구치 치근막 압축부위보다 더 넓고 압축력의 크기도 더 크게 나타났다. 또한tip back bend정도가 클수록 압축력도 크고 압축부위도 더 넓게 나타났다. 4.대구치 치근막의 압축력은 소구치 치근막의 압축력보다 상대적으로 더 작게 나타났다. 5.Ⅱ급 고무줄과 수직고무줄 적용 시를 비교해 보면 수직고무줄 장착시 전치부 치근막에 인장력이 더 넓게, 그 크기는 더 작게 나타났다. 반면에 구치부 치근막에 나타나는 응력의 분포와 크기는 별 차이를 보이지 않았다. 6.전치부 치근막 인장부위에서 인장력은 견치에서 제일 컸다. This study have been carried out to find out the mechnical effect of Multiloop Edgewise Arch Wire(MEAW) making use of the finite element method. The tip back bend of MEAW taken in this analysis is 5˚, 10˚ and 15˚. In addition, Class II or up & down elastic is applied to find out stress distribution and their values in PDL. A adult male of normal occlusion was selected to create the models of teeth and PDL. And the model of MEAW was also created using commercial finite element code (ANSYS version 5.2). The MEAW is forcibly engaged with a class II or up & down elastic, to determine the initial stress generated in PDL. Comparing the compressive and tensile stress at each reference-planes, following results are obtained. 1.When a MEAW of 5˚, 10˚, 15˚ tip back bend was engaged with Class II or up & down elastic, the distribution of compressive, tensile stress in entire PDL is similar in each case. 2.The values of compressive and tensile stress in PDL is higher in 15˚ tip back bend case than in 10˚ or 5˚ tip back bend case. 3.In the distal PDL of 1st and 2nd molar, compressive stress appears. The compressive area is more wide and its values is higher in PDL of 2nd molar than those in 1st molar. The compressive area and its values become more wide and higher according to the increase of the tip back bend. 4.The values of compressive stress are comparatively smaller in PDL of molars than those in premolars. 5.Comparing class II and up & down elastic case, tensile stress values in anterior teeth PDL are smaller and their distribution is more wide in up & down elastic case than class II elastic case. On another hand, there is no difference in distribution and stress values in PDL of posterior teeth between two cases. 6.Comparing the tensile area in PDL of anterior teeth, tensile stress values are maximum in PDL of canine.

본 연구에서는 3차원 정육면체 가열로 내의 전도-대류-복사 복합열전달 특서을 해석하였으며, 연소가스의 유입속도, 벽면의 반사율과 매체의 흡수계수 등과 같은 인자들의 변화에 따른 영향을 살펴보았다. 가열로의 벽면들은 단열되어 있고 가열로 내부로 일정한 온도의 연소가스가 유입될 때 시스템 내부의 온도는 유입 온도와 비슷하게 균일한 온도 분포를 갖는 것으로 예측할 수 있었다. 유입 속도가 증가하더라도 가열로 내부의 온도에는 거의 영향을 미치지 않았으며, 가열로는 유입되는 연소가스의 흡수계수가 증가할수록 가열로 내부의 온도는 보다 균일하게 된다. 또한, 가열로 내부 벽의 반사율이 커질수록 벽의 온도는 감소하고 또한 벽면에 작용하는 유효복사열유속은 증가함을 알 수 있었다. 이러한 해석 결과로부터 가열로 내부의 온도 분포는 매체의 흡수계수가 클수록 그리고, 벽면 반사율이 작을수록 일정하게 유지될 수 있다는 것을 알 수 있었다. 그리고 이러한 결과들을 종합하여 볼 때 가열로의 설계 시 일정한 열의 유입과 가열로를 단열시키는 것이 중요하며, 그리고 매체의 흡수 계수를 크게 하고, 그리고 벽면의 반사율을 작게 하는 것은 가열로 내부의 온도를 일정하게 유지할 수 있는 중요한 조건이 된다는 것을 알 수가 있었다.

The purpose of this study is to assess the postoperative stability and the tendency of relapse after both sagittal split ramus osteotomy in skeletal class III with anterior open bite. This retrospective study was based on the examination of 15 patients, 6 males and 9 females, with a mean age 23.1 years. The patients were divided into two groups based on the amount of preoperative overbite(group I:<1mm, group II:≥1mm). Serial lateral cephalometric radiographs were taken within 2 weeks preoperatively, within 1 week postoperatively and at a follow up period that ranged from 7 to 24 months postoperatively. All cephalometric radiographs were traced and digitized using the Quick ceph image Pro for analysis. And then, horizontal and vertical changes of reference points(B point, Pogonion, L1) were assessed by the linear measurements in millimeters on both axes. The results were as follows : 1 Mean horizontal relapses were 0.67±0.93mm (11%) at B point (P<.05) and 0.81±1.01mm (13.2 %) at Pogonion (P<.01). 2, Mean vertical relapses were 0.63±1.62mm (33.3%) at B point and 0.53±1.95mm (31.4%) at Pogonion (P>.05) 3. The mean angular change of occlusal plane to SN was 0.24±1.19 (P>.05) and that of mandibular plane to SN was 1.03±1.85 (P<.05). 4. There was correlation between the extent of preoperative overbite and the postsurgical relapse at B point and Pogonion. 5. There was no correlation between the amount of surgically produced horizontal movement and the postoperative horizontal relapse at B point.
